But I don't give a hoot that you are "having a busy Monday," your child "took 30 minutes to brush his teeth," your dog "just ate an ant trap" or you want to "save the piglets." And I really, really don't care which Addams Family member you most resemble. (I could have told you the answer before you took the quiz on Facebook.)

Here's where you and I went wrong: We took our friendship online. First we began communicating more by email than by phone. Then we switched to "instant messaging" or "texting." We "friended" each other on Facebook, and began communicating by "tweeting" our thoughts—in 140 characters or less—via Twitter.

All this online social networking was supposed to make us closer. And in some ways it has. Thanks to the Internet, many of us have gotten back in touch with friends from high school and college, shared old and new photos, and become better acquainted with some people we might never have grown close to offline.

Last year, when a friend of mine was hit by a car and went into a coma, his friends and family were able to easily and instantly share news of his medical progress—and send well wishes and support—thanks to a Web page his mom created for him.

Like many people, I'm experiencing Facebook Fatigue. I'm tired of loved ones—you know who you are—who claim they are too busy to pick up the phone, or even write a decent email, yet spend hours on social-media sites, uploading photos of their children or parties, forwarding inane quizzes, posting quirky, sometimes nonsensical one-liners or tweeting their latest whereabouts. ("Anyone know a good restaurant in Berlin?")

One of the big problems is how we converse. Typing still leaves something to be desired as a communication tool; it lacks the nuances that can be expressed by body language and voice inflection. "Online, people can't see the yawn," says Patricia Wallace, a psychologist at Johns Hopkins University's Center for Talented Youth and author of "The Psychology of the Internet."

But let's face it, the problem is much greater than which tools we use to communicate. It's what we are actually saying that's really mucking up our relationships. "Oh my God, a college friend just updated her Facebook status to say that her 'teeth are itching for a flossing!'" shrieked a friend of mine recently. "That's gross. I don't want to hear about what's going on inside her mouth."

That prompted me to check my own Facebook page, only to find that three of my pals—none of whom know each other—had the exact same status update: "Zzzzzzz." They promptly put me to "zzzzzzz."

This brings us to our first dilemma: Amidst all this heightened chatter, we're not saying much that's interesting, folks. Rather, we're breaking a cardinal rule of companionship: Thou Shalt Not Bore Thy Friends.

"It's called narcissism," says Matt Brown, a 36-year-old business-development manager for a chain of hair salons and spas in Seattle. He's particularly annoyed by a friend who works at an auto dealership who tweets every time he sells a car, a married couple who bicker on Facebook's public walls and another couple so "mooshy-gooshy" they sit in the same room of their house posting love messages to each other for all to see. "Why is your life so frickin' important and entertaining that we need to know?" Mr. Brown says.
